Alto's post office was established
1907 and discontinued in 1933. The origin of the name Alto, which means
"high", is not known. There were few hundred residents of this
town and gold was the mainstay. Today there are scattered ruins.

Alto, like Salero in Santa Rita Mountains dated back to after arriving
of Spanish Jesuits in 1690. Like Salero, reopen after Gadsden purchase.
Goldtree mine, named after Joseph Goldtree, grounded in 1875 known as
Tyndall Mining District. The original name was El Plomo (from Spanish
lead). Later (date is unknown) the name were changed to Alto (from Spanish
high), maybe because the mining was possible to see from the town. Now
is only one building and former post office (1907-1933) left. Alto is
worth to visit because there is beautiful high desert panorama view. Bobby
